With regard to sūtra that can be translated as the Wholesome teaching (Fan Shan-Y’ü-chiao) in terms of teaching, practice and principle, Chih-i asserts that the teaching of the Worldly Siddhānta is the teaching of wholesome words (seeing that the Buddha, in order to suit the capabilities of beings, focuses on encouraging sentient beings to cultivate wholesomeness within them for obtaining good effect); the Siddhānta for Each Person, and the Siddhānta of Counteraction are the teaching of wholesome practice (as the Buddha teaches sentient beings the methods of cultivating wholesomeness and destroying evil within them); and the Siddhānta of the Supreme Truth is the teaching of wholesome principle (as the Buddha addresses beings truth of liberation).
